Put a pipe into the middle or low middle of spent fuel bay, pump the water with a strainer and an ion exchanger and a heat exchanger and back to the spent fuel bay.

The strainer should be able to be replaced easily when plugged.

The ion exchanger should also be able to be replaced easily.

Step 2: build more partial circulation as specified in the step 1.

Step 3: decontamination the site.

Nuclear Industry should learn lessons from this accident, and  following could be some of them: 

  • Reevaluate and abandon the mode of multi-reactor operation. The cost efficiency could be maximized with several reactors in the same site, but the safety could be impacted.
  • The spent fuel should be removed more quickly from the nuclear power plant. The spent fuel pool which previously could store 10 core spent fuels should only store in the future about 6 core spent fuels.
  • Standby diesel generators or at least one of them should be moved from ground to underground, some people would think by instinct that the diesel generators should be placed in a higher building, actual an underground place is usually more safe.
  •  More research is needed on how to move the decay heat more safely and efficiently, and how to minimize the decay heat of fuel and spent fuel.
